Its modulus of elasticity and its strain energy at the yield point is 0.669N m
What is its modulus of elasticity?In order to resolve this issue, we must first define each of the provided variables before determining the object's modulus of elasticity. Finally, we will determine the system's net energy after calculating the deformation per unit of elastic volume. Starting now, let's define the variables.
Yield The specimen's metal's strength
S = 134 Mpa
Yield Epsilon el, the specimen's strain, is 0.003.
The test specimen's diameter, d 0, is 12.8 mm.
The specimen's gauge length, L 0, is 50mm.
Intensity of elasticity
E=SepsilonEl E= (414Mpa)/0.002 E=207Gpa
At the elastic limit, the strain energy per unit volume is
S el * epsilon el U el prime = 1 2 U el prime = 1 2.8 (134) (0.003)
U el prime =134kN* m/m 3
Taking into account.
Given that the sample's net strain energy is U el = U el prime (Volume of sample).
Volume of sample, Uet U, equals Uet=U() (Lo)
Uel = (134) ([tex]\pi[/tex]*0.0128/4) (50*10-3)
Uel = 0.669N m

How a washing machine works (from Wikipedia) All the important parts of the clothes washer are electrically controlled, including the inner drum, the valves, the pump, and the heating element. The programmer is like the conductor of an orchestra, switching these things on and off in a sensible sequence that goes something like this: 1. You put your clothes in the machine and detergent either in the machine itself or in a tray up above. 2. You set the program you want and switch on the power. 3. The programmer opens the water valves so hot and cold water enter the machine and fill up the outer and inner drums. The water usually enters at the top and trickles down through the detergent tray, washing any soap there into the machine. 4. The programmer switches off the water valves. 5. The thermostat measures the temperature of the incoming water. If it's too cold, the programmer switches on the heating element. This works just like an electric kettle or water boiler. 6. When the water is hot enough, the programmer makes the inner drum rotate back and forth, sloshing the clothes through the soapy water. 7. The detergent pulls the dirt from your clothes and traps it in the water. 8. The programmer opens a valve so the water drains from both drums. Then it switches on the pump to help empty the water away. 9. The programmer opens the water valves again so clean water enters the drums. 10. The programmer makes the inner drum rotate back and forth so the clean water rinses the clothes. It empties both drums and repeats this process several times to get rid of all the soap. 11. When the clothes are rinsed, the programmer makes the inner drum rotate at really high speed—around
80mph(130 km/h)
. The clothes are flung against the outside edge of the inner drum, but the water they contain is small enough to pass through the drum's tiny holes into the outer drum. Spinning gets your clothes dry using the same idea as a centrifuge. 12. The pump removes any remaining water from the outer drum and the wash cycle comes to an end. 13. You take your clothes out and marvel at how clean they are! 14. But there's still the problem of drying your wet clothes to figure out
The embedded computer system controls the washing machine by programming a sequence of steps that precisely control the water valves, heating element, inner drum rotation, and pump to wash and spin the clothes clean.
a) What are the inputs devices?The inputs devices for the controller of a washing machine would include the detergent tray, the power switch, the program selector, the thermostat, and the heating element.
b) What are the outputs?
The outputs for the controller of a washing machine would include the water valves, the inner drum, the pump, and the high-speed spin of the inner drum.
c) Name at least two safety features to include and specify
Two safety features that could be added to the controller for a washing machine are a temperature monitor and a motor overload protection. The temperature monitor would ensure that the water temperature does not exceed a certain threshold, while the motor overload protection would ensure that the motor does not become overloaded when running at high speeds. Both of these safety features could be implemented with software.
d) Describe a useful feature which could you add in software without requiring additional hardware.
A useful feature that could be added in software without requiring additional hardware is a timer. This timer would allow the user to set the machine to run at a certain time, allowing them to take advantage of lower electricity prices at certain times of the day.
e) Describe two useful energy-saving features which could you add in software if the controller could keep track the time of day
Two useful energy-saving features that could be added in software if the controller could keep track of the time of day are a delayed start and an off-peak washing cycle. The delayed start would allow the user to set the machine to run at a later time, allowing them to take advantage of lower electricity prices at certain times of the day. The off-peak washing cycle would allow the machine to run at a lower power setting and for a longer period of time when electricity prices are lower, resulting in energy savings.
f) Describe a useful feature which could you add in software if the machine included an internet connection
A useful feature that could be added in software if the machine included an internet connection is remote monitoring and control. This would allow the user to monitor and control the washing machine from anywhere in the world, allowing them to start and stop the machine, adjust settings, and receive notifications.

50 lossless wire terminating in a purely resistive load has a voltage-to-wave ratio of 3. Possible values of ZL are 150 ohms and 50/3 ohms.
To find the possible values of load resistance (ZL) that result in a voltage-to-standing wave (VSWR) of 3 in a 50-ohm lossless transmission line, we can use the following formula:
VSWR = ( 1 |Γ| ) / (1 - |Γ|)
where Γ is the reflection coefficient at the load, obtained as follows:
Γ = (ZL - 50) / (ZL 50 )
For VSWR to be 3, we can solve the above equations |Γ| = 0.5 which gives:
0.5 = |(ZL - 50) / (ZL
Squaring both sides and rearrangement gives:
ZL^2 - 50ZL - 2250 = 0

Which of the following material-specific parameter does the Einstein relationship explicitly describe Temperature Density of states of charge carriers Mobility of charge carriers None of the above
The Einstein relationship explicitly describes the mobility of charge carriers.
The Einstein relationship is a fundamental relationship in solid-state physics that connects the mobility of charge carriers to the temperature. Mobility refers to the ease with which charge carriers, such as electrons or holes, can move through a material.
The Einstein relationship states that the mobility of charge carriers is inversely proportional to the temperature. In other words, as the temperature increases, the mobility of charge carriers decreases. This relationship arises from the thermal energy in a material, which increases with temperature. Thermal energy provides the energy necessary for the charge carriers to overcome obstacles and move through the material. As the temperature increases, the thermal energy also increases, making it more difficult for the charge carriers to move, thus reducing their mobility.
The Einstein relationship provides important information about the behavior of charge carriers in a material, which is crucial in the design of many electronic devices such as transistors, diodes, and solar cells.

please explain the effectiveness of linear and binary searches on both ordered and unordered arrays.
Linear search is effective for both ordered and unordered arrays, since it looks through every element of the array in order until it finds the element that it is searching for.
On the other hand, binary search is much more efficient when searching through an ordered array, since it can quickly narrow down the range of elements that it needs to look through. Binary search is not effective when searching through an unordered array, since it requires the array to be sorted first before it can begin searching.

a u-shaped clevis holds a pin that connects to a single flat bar (like the connection at pin a of the two-link truss). what describes the loading configuration of the pin?
To prevent wear and lower the likelihood that either the pin or the clevis may fail, clevis pins should be tightly fitted to the holes in the clevis.
Threaded and unthreaded clevis pins are the two primary varieties. Unthreaded clevis pins feature a domed head on one end and a cross-hole on the other. A split pin or cotter pin secures the clevis pin in place (used in the USA). A formed head and a partially threaded shank are characteristics of threaded clevis pins. When putting the pin into the shackle, the formed head's cross-holed flat tab and lip act as a stop. Because of the flattened tab and the cross-hole, the pin may be moused easily during installation.
Although a bolt can serve as a clevis pin, it is not designed to withstand the lateral force that a clevis pin must withstand. While clevis pins and bolts are made to endure shearing forces, normal bolts are made to bear tension stresses.

determine the percent finer than each sieve and plot a grain-size distribution curve. b. determine d10, d30 and d60 from the grain-size distribution curve. c. calculate the uniformity coefficient, cu and coefficient of gradation, cc.
The percent finer than each sieve can be determined by calculating the cumulative percent finer for each sieve size.
what is sieve size?
Sieve size is a measure of the size of the particles that can pass through a sieve. It is usually expressed in the form of a number, which indicates the size of the particles that can pass through the sieve.
a. The percent finer than each sieve can be determined by calculating the cumulative percent finer for each sieve size. This can be done by adding the percentage of particles between each sieve size to the cumulative percent finer for the preceding size. The cumulative percent finer for the smallest sieve size is 0. To plot a grain-size distribution curve, the cumulative percent finer for each sieve size is plotted against the sieve size on a logarithmic scale.
b. The d10, d30, and d60 values can be determined from the grain-size distribution curve by finding the points where 10%, 30%, and 60% of the sample is finer than the sieve size.
c. The uniformity coefficient, cu, is calculated by dividing the d60 value by the d10 value. The coefficient of gradation, cc, is calculated by dividing the d30 value by the d10 value.

why does my lenovo laptop lose battery percentage when i have it contantly plugged in on coservation mode
At 60%, the battery is essentially removed by Conservation Mode, which then allows it to soul to 55%. It may take several days or weeks for 5% of a charge to be lost. The cycle is then replayed.
How can I keep a good laptop battery?Lithium-ion cells degrade with time and operation, just like all batteries do. Try to maintain the battery capacity between 20% and 80% numerous times a week rather than using your smartphone for a brief period of time after plugging it in to recharge it to help improve battery life and performance.
Does the battery suffer from conserve mode?The battery may be completely filled to 100% by disabling Preservation Mode, but altering this setting may shorten the battery's lifespan.

calculate the total deformation in a 25ft long, 4 in. diameter steel bar hanger that supports a 390 kip load. this bar is also subjected to a change in temperature from 140of before loading to -10of after loading, calculate the change in length due to temperature change. (esteel
The variation in length caused by temperature, according to the supplied statement, is 0.2925 inch.
How would you define the deformation?A alteration in shape put through the application of pressure is referred to as deformation. It is understood that even very small stresses can cause some deformation. When an outside load applied on an item, deformation happens. Crumpling, twisting, pulling, or tearing the object apart may be required to accomplish this.
Length = 25ft = 300 inch
Diameter = 4 inch
Load (P) = 390 kips = 390000lb
Initial temperature = 140°F
Final Temperature = -10°F
ΔT Change in temperature = -10 - 140 = -150°F
Modulus of elasticity E (steel) = 30 * 10⁶ psi
Coefficient of thermal expansion = 0.0000065inch/F°
